土壤固化/稳定化修复技术应用研究进展

 固化/稳定化（S/S）技术作为一种高效的固体废物处理技术近年来在污染土壤修复领域备受关注。本文介绍了土壤S/S修复技术的概况，其针对的污染物不仅包括重金属，也包括其他有机污染物。常用的土壤S/S修复材料主要有硅酸盐水泥类材料及各类添加剂；常用的土壤S/S修复技术分为异位和原位2种操作方式。结合美国超级基金修复项目报告，对土壤S/S修复技术在国内外污染土壤修复领域的应用情况进行介绍和分析。针对土壤S/S修复技术的优缺点，对该技术未来的发展需求进行了展望。

Research progress in solidification/stabilization technology for contaminated soil remediation

Solidification/stabilization (S/S) technology is a well-established remediation technology for contaminated soil. In this paper, the contaminant types, remediation ingredients, and delivery methods related to this technology are described. S/S technology is applicable to both organic and inorganic pollutants. Portland cement materials and various additives are the widely applied remediation ingredients used in S/S processes. On the other hand, S/S technology is applicable not only to in situ process but also to ex situ process. What’s more, according to the Superfund Remedy Report of EPA, the application of S/S in soil remediation is introduced and analyzed. Finally, the need for further research and development of S/S is emphasized in order to overcome different challenges.
